Summary
This quote means that being excessively open-minded can result in not being able to form strong beliefs or convictions. When someone's mind is too porous, it easily absorbs various perspectives and ideas without thoroughly evaluating or discerning them. As a result, it becomes difficult for them to develop or maintain a firm stance on any particular issue. While being receptive to different opinions is valuable, this quote cautions against becoming so excessively open-minded that one lacks the ability to hold strong convictions based on their own critical thinking and evaluation.
